Any of these will work:

Flywheel:

As was already said, there is only one size. In fact, I am using the clutch/flywheel I had in my '92 Si in my '97 SH now. I wrecked the '92 after only about 5k miles on it. When I knew I was buying a 5th gen, I looked at all the parts I had in my 4th gen that could be transferred over and saved them for my new car. So even between the 4th and 5th gen Preludes there is only one size.
If you put the links up to the clutches you are talking about, maybe someone would look at it and tell you their opinion on whether it is b.s. or a typo or what......
